I remember a similar situation when Alien: Resurrection (game) was announced for the Sega Dreamcast during the development of the PSX version. When word came through that the Dreamcast wasn't long for its lifespan though, the developers canceled the game...even though it was said to be the most polished version that would've come out.
In all honesty, those mini games don't sound fun at all. There isn't really any need to find ways to overcomplicate FPSs on any platform. We (finally) got ACM and regardless of what we think of it, I think we are fortunate to have even gotten the game all considering the development hell it was in for all those years.
